"Genetics, I am Your father"
He was the father of modern genetics
Who was Johann Mendel or Gregor Mendel?
This modernized term for "factors" determining traits
What are alleles?
These are used to tell you everything you need to know about the animals being studied
What are symbols?
This is known as the ratio of the different phenotypes in the offspring of a genetic cross
What is the phenotypic ratio?
When an organism has a certain characteristic that is always passed on to its offspring
What is true breeding?
This was the famous physicist under whom Mendel studeied at the University of Vienna
Who was Johann Christian Doppler?
What is the Dominant allele?
This was the factor experimented with that affected the color of radish leaves
What are environment factors?
Females only produce one of these each month for fertilization
What is an egg?
A genotype with two different alleles
What is a heterozygous genotype?
The number of pea plant characteristics Mendel studied
What is seven?
Using these can help predict the possible genotypes and phenotypes produced
What are Punnett Squares?
This determines the size of a Punnett Square
What are the genotypes present in each parent?
This kind of organism has both a dominant and recessive allele paired together
What is a hybrid organism?
This involves breeding an organism displaying the dominant phenotype but unknown genotype with a homozygous recessive organism
What is a testcross?
Mendel spent most of his life battling this
What is freedom of religion (or what is taxing of monasteries)?
This is the reason that animals have two alleles for each genetic trait
What are diploid cells?
In the offspring of a dihybrid cross, the probability that they will express both dominant traits is always this ratio
What is 9/16?
Mendel failed this twice
What is a teaching examination?
This is a diagram that follows a particular phenotype through several generations
What is pedigree?
Each organism has not one but two of these which determine its traits
What are factors (later renamed alleles)?
In the end, the genotype of the offspring is determined by which of these fertilizes the egg
What is sperm?
This states that alleles for different traits assort independently of one another during gamete formation
What is the law of independent assortment
This is what Mendel called true-breeding plants
What are purebreds?
A cross between two individuals, concentrating on only one definable trait
What is a Monohybrid cross?
